1. Discuss von Baerâs laws using examples of how early embryologists contributed to a phylogenetic approach to evolution. Give two specific examples of organisms and discuss whether the developmental biologists were correct or not.
2. Explain the origin of the word âsyndromeâ and in that context discuss why a mutation in gene could lead to abnormalities in seemingly unrelated tissues in the later embryonic and adult stages. Be sure to discuss a specific gene and gene mutation.
3. Compare and contrast (similarities and differences) between allometry and isometry. Define these terms and give two examples stating the similarities and differences in each.
4. Give an example of a soluble diffusible substance that is released by cells and diffuses to affect other cells to make developmental changes. Name the substance, name the organism and discuss in complete detail the developmental event it regulates.
